As Kendo says, I may be able to offer some help, just ask any further questions and i'll do my best.
I researched using a tablet to control my camera here:

I use a Canon 60D, electric pan tilt head, and an asus yoga loaded with dslr controller.
With this set up i can pan and tilt the camera remotely. Through the tablet I can control my camera (white balance, iso, shutter speed, aperture etc) as well as use it as a live view and as a trigger to shoot the image.
Previously, I used a standard ballhead attached to my wheelchair, however I wanted more vertical range so now use a monopod and electric pan tilt head.
Coincidentally the top link in sphexx's post was my thread also haha!
I would recommend the disabled photographer's society. Their annual fee is well worth it. I have been a member nearly a year now, and went on a studio day with them about 3 weeks ago, which was a great experience.
If you have any questions, just ask. I've learned a lot from this forum and if what I've learned can help other people, that would be great.
